ABSTRACT:
A training device, for mounting to a standard door having a cutout at middle height, the door mounted in a door frame having a strike plate at middle height. A sliding box is mounted in the cutout for slidable motion toward and away from the strike plate. At least one spring is mounted between the sliding box and the cutout for biasing the sliding box toward the strike plate. The spring is selected to resist compression and thus motion of the sliding box away from the strike plate. The amount of resistance that the spring provides is equivalent to the amount of resistance presented by a doorknob and locking assembly on standard doors. Thus, a crowbar-like tool may be used to pry the sliding box away from the strike plate to open the door and simulate the force and action necessary to pry open any standard door.
